Metabolic Super Charge

Metabolism is the set of chemical reactions that happen in living organisms to maintain life. But when most people mention the word metabolism, they are usually referring to the aspect of metabolism that deals with the body's energy systems. Let's take a really quick look at how the body makes energy.

The Four Energy Systems
The body uses four energy systems to fuel itself and function optimally. The first system, known as ATP System (Adenosine Triphosphate), is our immediate source of energy actually stored in the muscle cell, and it is only good for quick and powerful movements that last under 30 seconds. No oxygen is necessary, and very little waste products are produced.

The second system resynthesizes the used up ATP from the first energy system, and is known as the PC System (phosphocreatine).  Once again oxygen isn't required and waste isn't produced. The human body can usually get from 30 seconds to a minute and a half of energy expenditure out of the PC system.

The third system is called the Lactic Acid System (Anaerobic Glycolysis). The Lactic Acid system breaks down glucose from inside the muscle and blood stream, and delivers that familiar burning sensation when muscles are overused. This system will provide energy for about about 1.5 minutes to 3 minutes.

The fourth system is known as the Oxygen System (Aerobic Glycolytic System).  It's main source of energy is stored carbohydrates and fat.  The system cannot work without oxygen present, as it's part of the chemical process necessary to create sustainable energy. The Oxygen System, if the activity is not too intense, can theoretically function indefinitely.

It's important to keep in mind that all 4 systems operate all the time, with much overlap. Be aware that it's the duration and intensity of any activity that will ultimately delegate which system is primarily used and relied upon to provide energy. While the timed sets of kettlebell lifting may routinely tap into all four systems, its metabolic value lies in the fact that it literally rides the edge between the fat burning O2 System and the first three, providing a whopping caloric expenditure. 

If you watch one of our regular members perform a set, it immediately becomes apparent why kettlebell lifting is a super effective fat burning tool, even without reading all the science behind the sets. Pushing around a twenty-six pound steel ball for twenty minutes is work, tapping into every muscle in the body.  Initial basic skills combined with logical and intelligent programming are necessary to get the most out of this effect, but minimal expertise provides the lifter with viable methodology to work at maximum capacity without stopping (or getting injured). When approached this way, Kettlebell Fitness has a metabolic super charge effect on the human body, especially when customized specifically for that purpose.
